Possible Cause
The service or site
called does not
support 56K or
supports an
incompatible 56K
implementation.
There is noise on the
telephone line.
The telephone line
does not support
56K implementation.
Solution
An internal modem
supports K56flex.
To find an Internet service
provider (ISP) that
supports K56flex, go to
the Compaq Web site at
www.compaq.com.
The 56K protocol of an
internal modem will fall
back to lower speeds if
the telephone line is too
noisy for a high-speed
connection.
Try using another
telephone line.
